HI guys, I am deciding if I need to spend the extra coin for the 4860 which is a slightly slower processor with more cores.

I work in medical devices and design stents, so though I don't have large assemblies, my individual parts are very hard on the machine.

I use solidworks mostly for modeling, but will also use it for photoview 360 and some very light simulation. Do I need the extra cores or should I just go for processor speed?

Also, where does the graphics card fall into this?

Any input would be really appreciated.
